The latest full compatibility with ie6, ie7, ie8, ff, and google The latest: http://www.chhua.com/web-note762 The chaos in the browser market has caused a lot of trouble for designers. After the design page is compatible, the browser must be compatible with that browser. The compatibility between ie6 and ff is easy to solve. It will be troublesome to add ie7, and the emergence of ie8 will be even more trou

after the data is valid. This means that the clock signal goes first, and the data signal goes back. Sometimes latches are used as data latches in some memory circuit.Disadvantages:Time Series Analysis is difficult. There are two reasons for not locking latches:1. latches are prone to glitches. 2. latches are simpler than FF in ASIC design, but most devices do not have latches in FPGA resources, therefore, a logical gate and

The dynamic verification code is used in the logon window. Code: Corresponding JS Function refreshcode (){Document. getelementbyid ("checkcode"). src = "authimg"; (or new date ())} Result: The verification code image in IE 6 can be refreshed, but cannot be refreshed in IE 7 and ff. Cause: After analysis, because the SRC specified by JS is the same as the SRC of the original image, the refreshing mechanism of IE 6 is differe

The implementation of childnodes in IE and FF is different in terms of node computing.IE ignores the carriage return and line feed, while FF uses the line feed as a node, for example: Div ID="Node"> A Href="Default. aspx" >AA> Div>1Div> Div> Div ID="Node">A Href="Default. aspx" >AA>Div>1Div>Div> CodeIn IE, The Length attribute of Node 1 is 2, and the Length attribu

Another tangle of one night, the same font and size, the height in IE and FF is not the same solution. I have never wanted to use hack, which is equivalent to virus attacks (to overcome bugs with bugs ~ _~! Color: # 0000ff \ 9;/* IE6, IE7, IE8 */* Color: # FFFF00;/* IE6, IE7 */_ Color: # ff0000;/* IE6 */ As for why \ 9 [IE6-IE8], I don't know. Really! However, when \ 0 is used, only IE8 is recognized. Therefore: . Test {Color: #000000;/*

See the following code: String mac_no_ff = ""; for (int i = 0; i ) { + = integer.tohexstring (Card[i] 0xFF). toUpperCase (); + = integer.tohexstring (card[i]). toUpperCase (); } System.out.println (MAC); System.out.println (MAC_NO_FF);This is the output .286ED488C8C3286EFFFFFFD4FFFFFF88FFFFFFC8FFFFFFC328 normal conversion, 6E after the conversion of a series of FF this is because the receive

First, only the browser is differentiated, regardless of the version Copy codeThe Code is as follows:Function myBrowser (){Var userAgent = navigator. userAgent; // obtain the userAgent string of the browser.Var isOpera = userAgent. indexOf ("Opera")>-1;If (isOpera ){Return "Opera"}; // Determine whether the operabrowser is usedIf (userAgent. indexOf ("Firefox")>-1 ){Return "FF ";} // Determine if the Firefox browser is usedIf (userAgent. indexOf ("Chr

In IE, event objects are saved and maintained as a global variable. All browser events, whether triggered by the user or other events, update the Window.event object. So in the code, as long as easy to call Window.event can easily get the event object, and then event.srcelement can get trigger event elements for further processing in FF, the event object is not a global object, in general, is the scene, on-site use,

When you add a default property for a child node: Childnode.classname = "ChildClass"; Or: Childnode.classname = new String ("ChildClass"); Parentnode.innerhtml ie,ff can get [ When you add a private property to a child node: Childnode.type = "Childtype"; Parentnode.innerhtml when and only if IE can get [Childnode.type = new String ("Childtype"); Object objects Parentnode.innerhtml IE,FF is not available [ C

IE under the onmouseenter and OnMouseLeave to solve. Unfortunately, FF is not. I think again, why such a good function, why FF do not quote it? There are IE in the onpropertychange, ah, FF did not ... A section of JS is introduced in the contrast example to accommodate FF Onmouseenter and OnMouseLeave. ： Copy C

After testing, we found that the jitter of Example 1 in ff is severe, and that in ie is a little bit. The specific cause is actually caused by the bubble mechanism of mouseout. Http://www.cssrain.cn href = "http://www.cssrain.cn/attachments/month_0807/f2008715193530.jpg" rel = lightbox> In IE, there are onmouseenter and onmouseleave. Unfortunately, ff does not. I want to explain again, why does

In a recent project, there is a function: There is a checkbox on the page. When the user selects or cancels the checkbox, A jsonp request is sent to the backend. At that time, the implementation was to add an onchange event for this checkbox, but the results were unexpected. For this reason, I have studied it in depth, the following problems exist in the performance of the onchange event in IE and FF. Question ①:In

In ie, event objects are saved and maintained as global variables. All browser events, whether triggered by the user or other events, will update the window. event object. Therefore, in the code, you only need to easily call window. event, you can easily obtain the event object, and then event. srcElement can be used to obtain the element that triggers the event for further processing in ff, but the event object is not a global object. Generally, it o

= document. getElementById ("header ");Var myAttribute = myObject. getAttribute ("class "); In addition, when setAttribute () is used to set the Class attribute, the two browsers also have the same difference. The Code is as follows: SetAttribute ("className", value ); This method applies to all IE versions earlier than IE8.0. Note: IE8.0 does not support the "className" attribute. SetAttribute ("class", value); applicable to IE8.0 and firefox. [Compatible processing] Method 1 and both are

I should be tired after the night package, but I still have the strength to beat these characters. It seems that I have not reached this point yet.To put it bluntly, I recently wrote an online editor, which is similar to ewebeditor. Of course, it is not as powerful as other people, but has basic skills and is compatible with ie and ff, I have also spent a lot of effort on this, so let's sacrifice the code.Demo.html:Copy codeThe Code is as follows:Font

This article will introduce the differences between window. event objects in js and ie and ff. If you need to know what to learn, you can refer to them. 1. The event object is valid only when an event occurs. Some Properties of the event only make sense for specific events. For example, the fromelement and toelement attributes only make sense for onmouseover and onmouseout events.1. window. eventIE: window. event objectFF: There is no window. event ob

Compatibility tips:1, FF under the div set padding will cause width and height increase, but IE will not. (Can be solved by!important);2, center question: 1). Center vertically. Set Line-height to the same height as the current Div, and then through Vetical-align:middle. (Note that the content does not wrap.).2). Center horizontally. margin:0 Auto; (of course not everything).3, if you need to give the contents of a tag style, you need to set display:b

In the same login code, there is no problem in ff, and ie won't work .. Logon page: login. php has three pages. if you want to open the other two pages, you will first jump to the logon page if you do not log on. After the user name and password are entered correctly, save the password to the session. you can freely browse various pages without having to log on again. Ff is normal, and the implementation is

The following lists the differences between the JAVASCRIPT writing methods of IE and FF in development, which are constantly updated and accumulated ,! 1. judge the browser: If it is IE, then window. navigator. userAgent. indexOf ("MSIE")> = 1 The result is TRUE; if it is FF, then window. navigator. userAgent. indexOf ("Firefox")> = 1 indicates that the result is TRUE. 2. determine the next node: If the

;}}/* Firefox */@-Moz-document url-prefix () {. sofish {padding: 11px ;}/ * all firefox */Html>/**/body. sofish, x:-moz-any-link, x: default {padding: 11px;}/* newest firefox */[/Css]Then, we can also find the second method. Use IE comments on the body class instead of adding separate Or@importIt will be a better choice. Although file splitting is also a good choice, but for the page loading speed, HTTP requests can not be wasted.It is not recommended to use JS or backend programs unl
